Detailed Description

Class that represents the LC_DYSYMTAB command.

This command completes the LC_SYMTAB (SymbolCommand) to provide a better granularity over the symbols layout.

Member Function Documentation

◆ accept()

void LIEF::MachO::DynamicSymbolCommand::accept ( Visitor & visitor ) const

overridevirtual

Implements LIEF::Object.

◆ clone()

DynamicSymbolCommand * LIEF::MachO::DynamicSymbolCommand::clone ( ) const

overridevirtual

Reimplemented from LIEF::MachO::LoadCommand.

◆ external_reference_symbol_offset()

uint32_t LIEF::MachO::DynamicSymbolCommand::external_reference_symbol_offset ( ) const

Byte offset from the start of the file to the external reference table data.

This field seems unused by recent Mach-O loader and should be set to 0

◆ external_relocation_offset()

uint32_t LIEF::MachO::DynamicSymbolCommand::external_relocation_offset ( ) const

Byte offset from the start of the file to the external relocation table data.

This field seems unused by recent Mach-O loader and should be set to 0

◆ indirect_symbol_offset()

uint32_t LIEF::MachO::DynamicSymbolCommand::indirect_symbol_offset ( ) const

Byte offset from the start of the file to the indirect symbol table data.

Indirect symbol table is used by the loader to speed-up symbol resolution during the lazy binding process

◆ local_relocation_offset()

uint32_t LIEF::MachO::DynamicSymbolCommand::local_relocation_offset ( ) const

Byte offset from the start of the file to the local relocation table data.

This field seems unused by recent Mach-O loader and should be set to 0

◆ module_table_offset()

uint32_t LIEF::MachO::DynamicSymbolCommand::module_table_offset ( ) const

Byte offset from the start of the file to the module table data.

This field seems unused by recent Mach-O loader and should be set to 0

◆ nb_external_reference_symbols()

uint32_t LIEF::MachO::DynamicSymbolCommand::nb_external_reference_symbols ( ) const

Number of entries in the external reference table.

This field seems unused by recent Mach-O loader and should be set to 0

◆ nb_external_relocations()

uint32_t LIEF::MachO::DynamicSymbolCommand::nb_external_relocations ( ) const

Number of entries in the external relocation table.

This field seems unused by recent Mach-O loader and should be set to 0

◆ nb_indirect_symbols()

uint32_t LIEF::MachO::DynamicSymbolCommand::nb_indirect_symbols ( ) const

Number of entries in the indirect symbol table.

See also: indirect_symbol_offset

◆ nb_local_relocations()

uint32_t LIEF::MachO::DynamicSymbolCommand::nb_local_relocations ( ) const

Number of entries in the local relocation table.

This field seems unused by recent Mach-O loader and should be set to 0

◆ nb_module_table()

uint32_t LIEF::MachO::DynamicSymbolCommand::nb_module_table ( ) const

Number of entries in the module table.

This field seems unused by recent Mach-O loader and should be set to 0

◆ nb_toc()

uint32_t LIEF::MachO::DynamicSymbolCommand::nb_toc ( ) const

Number of entries in the table of contents.

Should be set to 0 on recent Mach-O

◆ print()

std::ostream & LIEF::MachO::DynamicSymbolCommand::print ( std::ostream & os ) const

overridevirtual

Reimplemented from LIEF::MachO::LoadCommand.

◆ toc_offset()

uint32_t LIEF::MachO::DynamicSymbolCommand::toc_offset ( ) const

Byte offset from the start of the file to the table of contents data.

Table of content is used by legacy Mach-O loader and this field should be set to 0
